Encountered error while generating package metadata

Initially I created an environment with python == 3.7 but the problem was that when installing the requirements, ipython==8.6.0 which requires python 3.8 or higher. This was clashing with the "Programming Language :: Python :: 3.7" in setup.py.

So I tried creating the environment with python == 3.9 (to be on the safe side) and changed "Programming Language :: Python :: 3.9"in setup.py. This results in a new problem:

  note: This error originates from a subprocess, and is likely not a problem with pip.

Do we keep python == 3.7 and deprecate the other packages?
